PATENT JOHN T. WARING, OF YONKERS, NEYV YORK.

SPECIFICATION forming part of Letters Patent No, 347,538, dated August17, 1886.

Application filed November 9, 1885. Serial No. 182,170. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN T. WVARING, of Yonkers, in the county ofVestchester and State of New York,-have invented a new and usefulImprovement in Apparatus for Mannfacturing Napped or Filled Yarns orThreads, of which the following is a specification.

My invention relates to apparatus for producing yarns or threads, whichare severally composed of two or more threads, yarns, rovings,orstrands, doubled and twisted together, and nap or filling materialsecured between them by the operation of doubling and twisting themtogether. Such napped or filled yarns may be employed in producing wovenor knitted fabrics, the surfaces of which will resemble natural furskins, or they may be employed in the manufacture of woven or knittedfabrics for other purposes. In producing such napped or filled yarns theseveral separate strands or threads which compose each yarn areconducted from spools or carriers to a twisting-spindle, by theoperation of which they are doubled and twisted together, and

the napor filling material is deposited upon one or more of the separatestrands before they are so twisted together, and by the operation oftwisting is caught and confined between the strands and caused to assumepositions radial to the napped or filled yarns.

In carrying out my present invention I provide a movable support forcertain of the strands in their passage from the carriers tothetwistingspindle, and I impart to this movable support apositive movementconforming to the travel of the strands, and I also employ afiber-supplying apparatus for delivering nap or filling material in aloose and free condition upon the one or more strands, while they areupon the support, which nap or filling material is secured in place whensaid one or more strands are intertwisted with the other threads orstrands which go to make up the completed yarn. I prefer to make themovable support in the form of a hollow body or cylinder having thoseportions with which the strands or threads come in contact made ofperforated or reticulated material, and by means of an exhaust-fan orother suitable apparatus I exhaust the'air fromthe interior of thehollow support or cylinder continuously.

Then the fiber which is delivered by the fibersupplying apparatus uponthe threads while they are moving with the hollow support or cylindercomes in contact-with the perforated or reticulated portions thereof, itis held thereon by the air rushing in through the perforated orreticulated portions, because of the partial Vacuum within the-supportor cylinder, and by this means I hold the fiber in place across thestrands which move in contact with the cylinder until such time as thosestrands are intertwisted with other strands and the fiber locked betweenthe twisted strands, when no other support for the fiber is necessary.In order to cause the strands or threads which receive the nap orfilling material upon them to move in contact with the cylinderthroughout a considerable portion of its circumference, I provide aguideroller, under which such strands pass, and I also provide a secondguide-roller, whereby other strands which do not receive nap upon them,but which combine with the former to produce the completed yarns, arecaused to travel in the same direction and adjacent to those strandswhich receive the nap or filling material upon them after the latterleave the cylinder.

The hollow cylinder may have large openings in its ends and be fitted torotate in airtight contact with beads which are formed with or securedto the frame of the machine, and the air may be withdrawn from withinthe cylinder through passages formed in such fixed heads, and which arein connection with the exhaust-fan.

My invention consists in novel combinations of parts, which arehereinabove referred to and are hereinafter more fully described, andpointed out in the claims.

In the accompanying drawings, Figure 1 is avert-ical section of anapparatus embodying my invention. Fig. 2 is a horizontal section andplan upon the plane of the dotted line as as, Fig. 1; and Fig. 3 is apartly-sectional elevation of the hollow cylinder and adjacent partsupon the plane of the dotted line y Fig. 1.

Similar letters of reference designate corre sponding parts in theseveral figures.

A A designate spindlesand fliers, which are arranged in suitablebearings, a a, and are rotated by spimlle-driving bands 1), receivingmotion from a drivingdrum, b, and driving onto the spindle-pulleys orwhirls If. I have shown a number of these spindles arranged side byside. \Vithin the fliers are bobbins c, which are connected bytraverse-rods c with the traverse-bar c. The traverse-bar c is fitted toslide upon guides c at its opposite ends, and receives a to-and-fromotion by means of arms 0 upon the rock-shaft The shaft 0* also has anarm, c", which engages with a cam, 0 upon the upright shaft 0, saidshaft being driven by means of a wornrwheel, c", from a worm, c, on theshaft of the spindle-driving drum 1). In lieu of the mechanism abovedescribed, any other suitable mechanism, such as is in ordinary use, maybe employed for imparting a proper traverse motion to the bobbins 0. Thespindles or fliers are each employed to double and twist together two ormore strands which are taken from spools (I. These spools are arrangedupon fixed spindles on jack-boards B B.

G designates a hollow cylinder, which is fixed upon a shaft, 0, mountedin suitable bearings, a", in side frames, D. Arranged adjacent to thecylinder 0 are guide-rollers d d, which are parallel with the axis ofthe cylinder. Certain of the strands or threads, 8, from the spools (Ipass beneath the guideroller d, and thence partially around thecircumference of the cylinder to the top thereof, and thence direct tothe fliers A. Other of the strands, s, pass from spools or bobbins (Zpartially around and beneath the guide-roller d, and from theguide-roller (1 they take the same course as the strands s to the fliersA. The circumference of the cylinder 0 may be of sheet metal or othermaterial, and at those points at which the strands 8 come in contactwith the periphery of the cylinder its outer wall or circumferenceshould be of perforated or reticulated metal, so that air may readilypass from the exterior to the interior of the cylinder. In making thecylinder its entire circumference may be of finely-perforated metal orof fine wire cloth or gauze, and all portions of its circumference,except narrow circumferential bands at those points where the strands 8pass around the cylinder, may be covered with paper or other material,to close the openings in its circumference.

As here represented, the cylinder has open ings c, of considerable size,in its ends, and is fitted to rotate in a more orless airtight coir tactwith fixed heads D',. which are formed with or attached to the sideframes, D, and are constructed with throats or passages c. The cylinder,as represented, is provided with hubs c", which are secured upon theshaft 0, and are connected with the integral portions of the ends bymeans of spiders or bridges c.

E designates an exhaust-fan or an exhauster, which, as here represented,is driven by a belt, 0", from a pulley, 0", on the driving-shaft E, andhas its air-inlet openings connected by pipes or passages c", with thepassages 0, formed in the cylindenheads D and the ad jacent frameportions. The exhuaster E has at its periphery an air-outlet, c and byits constant operation air will be rapidly drawn in through theperforated or reticulated portions of the cylinder circumference andexhausted from the cylinder through the passages e c. This operation ofthe exhauster will produce a constant inflowfof air through theperforated or reticulated portions of the cylinder eircuinference, andwill hold upon the surface of the cylinder the fiber deliveredthereupon, as more fully hereinafter described.

In connection with the twisting-spindles and the hollow perforatedvacuum-cylhuler I employ a fiber-supplying apparatus, which may be ofany suitable character. As here represented, this fiber-supplyingapparatus consists of the picker-cylinder F, rotating within the casingF, from which extends a delivery nozzle or conduit, F. It also comprisesa pair of feed-rollers, ff, arranged adjacent to the picker-cylinder F,and the feeding-aprouf passing around the lower feed roller,f, and asecond roller,f.

The picker-cylinder may be driven by a belt, f", passing around pulleysupon the shaft E and the shaft of the pieker-cylimler, and by means ofgearavlieelsf f", which are shown in Fig. 2, the picker-cylinder impartsmotion to thelowerfeed-roll,f. The blastof air produced by the rapidrotation of the picker-cylinder F will be sufficient to cause the fiberto be discharged freely through the outlet F and delivered upon thestrands s as they pass from the guide-roller d to the guideroller al andlie upon the circumference of the cylinder 0, as shown in Fig. 1. Thetravel of the strands s s is of course produced and controlled by thespeed of rotation of the bobbins c, and the cylinder 0 should have aspeed of rotation which will correspond to the speed of travel of thestrands, so that during the time the strands s are in contact with thecylinder they will have no movement relative thereto. The hollowcylinder is, as here represented, driven by means of a belt, {1, passingfrom the pulley I to a pulley, g", on the shaft C of the cylinder.

The spindledriving drum is, as here represented, driven by a belt, 71,from a pulley, h, on the driving-shaft E, and the shaft E, from whichall parts of the machine are driven, as before described, may beoperated by a driving-belt, h. (Shown in Fig. 1.)

By the continuous exhaustion of air from the cylinder there is produceda constant inflow of air from the circumference of the cylinder throughthe perforated or reticulated portions thereof, on which the strands .9lie, and an ample quantity of the fiber will by the inflow of air beheld in position on these perforated portions of the cylinder and uponthe strands which are in contact therewith to make the napped or filledyarns. As the strands s and the fiber which lies across the strands andis held in contact with the cylinder, as described, rcach theguide-roll-d the strands s are brought into play and serve to bind thefiber which constitutes the nap or filling material between the strandss s, and by the rapid rotation of the spindle and flier A A the strandss s are twisted together,the twist commencing at the guideroller d, andthe nap or filling material is thereby secured between the strands orthreads which compose the finished yarn.

I have here represented the finished yarn as produced by a singlestrand, 8, in connection with a single strand, 3, the former passingpartly around the'cylinder G, and the latter being combined therewith atthe guideroller (P,- but three or more threads or strands may beemployed in making the finished yarn, one strand, .9, being passedpartly around the cylinder, and two strands, 8, being combinedtherewith, or two strands, 8, may be passed partly around the cylinder,and one or two strands, 8, combined therewith to produce a finishedyarn. In order to assist the adhesion of the nap or filling material tothe strands or threads 8, such strands or threads or the nap or fillingmaterial may be moistened with water or otherliquid. N apped, filled, ortufted yarn, or even rope of considerable size, may be produced by myprocess. For the strands or threads which are to be twisted together Imay use wool, cotton, flax, hemp,variouskinds of grasses, wire,or narrowloosely-woven tape, and for the nap or filling material I may use anykind of fur, hair, grass, cotton, or wool waste, rags, excelsior, orwood shavings.

In order to prevent the free inflow of air through that portion of thecylinder 0 on which the strands 8 do not lie, it is desirable to employa shield to guard the openings and cut ofi' the inflow of air. I havehere shown a shield, I, arranged within the cylinder 0 and supportedloosely on the shaft 0 thereof. This shield extends upon the interior ofall that part of the cylinder on which the strands 8 do not lie, and inorder to hold it against ro tation with its opening opposite the part ofthe cylinder on which the strands do lie I weight it at its lower part,as shown at 0.

In the operation of my apparatus the napping or filling fiber isdeposited in aloose and free condition on the one or more threads orstrands s which are on the cylinder 0, and by this peculiarity mymachine or apparatus is distinguished from one which comprises cordsextending parallel with each other and both wound with silk or othermaterial, which is first cut with a knife and then carried around acylinder and between converging strands, which are twisted together toconfine between them the silk or other material brought by the saidcords within the grasp of the strands as they are being twistedtogether.
